CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 421,711, dated February18, 1890 Application filed September 2, 1889. Serial No. 322,774:- (Nomodel.)

To all whom it may concern.-

Be it known that we, SOLOMON HEYMANN and BERRY PROssER, of Fayetteville,in the county of Lincoln and State of Tennessee, have invented a new anduseful Improvement in Car-Couplings, of which the .following is aspecification.

Our invention consists in a new and improved car-coupling, which will behereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective viewof our improvement. Fig. 2 is a central vertical section thereof, andFig. 3 is a horizontal section of the same. Fig. 4 is a section of thebar 5.

The same numerals of reference indicate corresponding parts in all thefigures.

Referring to the several parts by their designating-numerals, 1indicates the end of a car which is provided with our new and improvedcar-coupling. Beneath the end of the car is secured a draw-bar 2, havingthe drawhead 3. This draw-bar is formed with the longitudinal openingat, in which fits a sliding bar 5, having the curved head 6 at its outerend, the ends of which come in contact with shoulders 7 at the rear endof the draw-head when the bar is slid back by the coupling- The forwardend of the sliding bar is formed on its lower side with a guide-lug 8,which slides in a guidegroove 9 in the bottom of the draw-head. Thelower 'side of the draw-bar is formed with a longitudinal slot 10,opening into the space at, and with bearing-lugs 11 11 on each side ofthis slot. The lower side of the bar 5 is provided with a rack or seriesof teeth 12.

Between the lugs 11 is centrally pivoted the lever 13, the innerupwardly-extending end of the middle part 14 of which is provided withthe curved rack of teeth 15, which interlnesh with the teeth on thelower side of the sliding bar 5. In the forward end of the curved lever13 is secured the lower end of the coupling-pin 16; or the pin and levermay be cast in one piece, which passes up through the usual apertures 17in the draw-head. The

sliding bar 5 is formed with a short longitudi nal slot 18,,and astop-pin 19 passes through the sides of the draw-bar and through thisslot and confines the movements of the sliding bar to the proper limits.To the rear end of the lever 13 are secured the lower ends of chains 20,which then pass under grooved pulleys 21 and up to levers 22, which canbe secured to the end of the car, so that the cars can be uncoupled fromtheir top or sides without going between them.

23 indicates a spring, which is secured at one end to the draw-bar andat the other end to the lever 13 at the point shown, by whicharrangement it will be seen that. this spring will operate to hold thelever in either its locked or unlocked positions, as shown in dottedlines in Fig. 2. When the rear end of the lever is raised, the curvedrack of teeth 15, meshing with the teeth 12 of the sliding bar 5, willslide the said bar forward, and at the same time the forward end of thelever draws the coupling-pin down. When two cars to be coupled cometogether, the end of the coupling-link comes in contact with the curvedhead 6 of the sliding bar 5, pushing the bar back, when the teeth, ofthe bar meshing with the teeth 15 of the lever, the front end of thelever will be raised, pushing the coupling pin up through the link. Itwill thus be seen that our invention will couple cars togetherautomatically, while they are uncoupled by raising the rear end of thelever 13, through the chain 20 and levers 22, without going between thecars.

241 indicates our coupling-link, which is flat on its upper side, but isbeveled or inclined upon the lower side of each end at 24 to cause it toreadily enter and slide up the inclined bottom of a draw-head, which isof especial value when the draw-heads are of slightly different heights.

Having thus described ourinvention, what we claim, and desire to secureby Letters Patent, is

1. In a car-coupling, the combination of the draw-head having the barformed with the longitudinal opening 4, the slot 10, and thebearing-lugs 11, the sliding bar having the head at its front end andthe series of teeth on its lower side, and the lever pivoted between thelugs 11 and having the curved rack 15 and having the coupling pin at itsforward end, substantially as set forth.

2. In a ear-coupling, the combination of the draw-head having the barformed with the opening 4:, the slot 10, and the bearinglugs 11, thesliding bar having the head at its front end and the series of teeth onits lower side, the pivoted lever having the curved rack 15 and havingthe coupling-pin atits forward end, and the spring secured at one end tothe draw-bar and at the other to the lever, substantially as set forth.

3. The combination of the draw-head having the bar formed with theopening 41, the slot 10, and the bearing-lugs 11, the sliding bar havingthe head 6 and the series of teeth on its lower side, the pivoted leverhaving the curved rack 15 and having the couplingpin at its forward end,the grooved pulleys 21, the chains 20, and the levers 22, substantiallyas set forth.

4:. The combination of the drawhead formed with the guide-groove 9 andthe shoulders 7, and having the bar formed. with the opening 4, the slot10, and the bearing-lugs 11, the sliding bar having the head 6, thebottom guide-lug 8, and the series of teeth 12, and the pivoted leverhaving the curved rack 15 and having the coupling-pin at its forwardend, substantially as set forth.

5. The combination of the draw-head having the bar formed with theopening 4, the slot 10, and the bearing-lugs 11, the sliding bar havingthe head 6 and the rack 12 and formed with the longitudinal slot 18, thetransverse stop-pin 19, and the pivoted lever having the curved rack 15and having the eoupling-pin at its forward end, substantially as setforth.
